Efficiency of grinding stabilizers in cement clinker

Grinding processes with fatty acid stabilizers are known as “dull” ones; the grinding time and grinding energy are comparably higher, but the grinding control need not be as strict as those processes in the presence of TEA. The use of fatty acid grinding stabilizers with their hydrophobic behavior is limited in the cement industry. _
